Can a fuel injection vapor lock?
Still, a modern fuel-injected system can suffer from vapor lock, not only if pressure in the fuel line drops (faulty fuel pressure regulator or fuel pump, for example) and the fuel line is subjected to high temperatures, but also modern engines that may reach between 248 and 284 F (120 and 140 C) using ethanol blended …
Why does vapor lock not occur in fuel injected engines?
Fuel-injected engines use a more volatile fuel that is easier to vaporize and mix with air for a much better combustion. So this new fuel has a lower boiling point. However, vapor lock rarely occurs in a modern engine because of the use of an in-tank, electric fuel pump.
What to do when your car has vapor lock?
After your warmed engine stalls, pull to the side of the road. Open the hood. Place a bag of ice on the fuel line between the fuel pump and carburetor and the one that connects to the fuel pump to bring down the fuel line’s temperature and allow vapor fuel to condense. After a few minutes, try starting the engine.
How can I get rid of vapor lock on my fuel pump?
Pouring cold water on the fuel pump will cool down the system in no time. Make sure the ignition is OFF while you do the process. The cold water will liquefy the vapors quickly. It removes the blockage of vapors present inside the fuel pump and lines.
When does a carburetor go into vapor lock?
Vapor Lock most frequently occurs when the engine is shut down. The problems we encounter is when we try to restart the hot engine. Heat rises. Most carburetors are on the bottom of the engine = cooler location while on the ground.

Is there vapor lock in a Chevy Impala?
Its boiling point is much lower than fuel blends of the past, and it’s more volatile. In a case where vapor lock is suspected, definitive diagnosis is key. In this example, the team is working on a 1960 Chevy Impala street cruiser with a 350-HP engine belonging to a North Carolina customer.
